Spanish sci-fi. The mutants are a totally whacked out gang of murdering robbers, including a Siamese twin pair. They accidentally murder all the guests at a wedding party to simply kidnap the bride. Race across the galaxy to a seedy bar on a barren mining planet to claim treasure, love, revenge, or freedom. Very darkly filmed-- it's a shame there isn't a brighter version for DVD. A cosmo bar helped make the original Star Wars the monster great film. A seedier place in American Astronaut was interesting, until the film degenerated in homoeroticism. Otherwise film has been pretty stingy with space bars. They receive more attention in TV sci fi. If you're interested in the theme, Accion Mutante is a film to see.
